These instructions add a countdown clock to the product page to show your customers when your sale ends, driving the urgency to purchase the product now before the discounted price ends. If you don't want a sales clock, these steps are not necessary.

These instructions are used when Product Discount and Product Upsell are used together, and this is necessary to ensure the discounted products that are only available in an upsell offer are not visible on your storefront. If you are not using Product Discount and Product Upsell together, these steps not necessary.
